I seem to have a problem with the headers and the footers, only the ones controlled via the admin.cgi. The ones used in the subscribers.cgi work fine. For example:

When I modify the headers and footers in the subscribers.cgi, all of the pages show propperly with the header at the top and the footers at the bottom in all of the subscribers.cgi admin pages.

When I modify the headers and footers in the admin.cgi, all of the text generated such as "The email address is invalid. Make sure you have inlcuded the @ and the domain." or "You have been subscribed to the list" show up above the header.

For the most part all of the header/footer stuff is exactly the same on both scripts. In this case my guess would be something you're doing with CSS, but since you said you have the same thing in both places, that doesn't seem like it would be the problem.
